Loopback issue ??

I have followed the howto and setup Fedora Core 5 and installed ISPConfig on it and all is working well, However just one issue if i can get some help please...

In the router i have i have port forwarded all the requred ports... And from outside the network the system is working perfect but i cannot access the webs that i create using the domain names from within the network ???/

for expmple when i put this domain in www.domain.com this works very well from any other internet connection... i can see the website... however from inside the network what happens is the routers login comes up asking me for a username and password for access to the router configuration.

You have to enable NAT LOOPBACK inside your router.
in zyxel-routers you connect throug telnet and in the commandline interface you first type :
IP NAT LOOPBACK ON //to enable it now
then you type :
SYS EDIT IP NAT LOOPBACK ON //to make it enabled at next bootup too
